Eurorack 3U

Three essential functions The 1:3 section is a buffered multiple, allowing a note CV to be distributed to up to 3 VCOs without voltage drop. The 2:2 section is a 2-input summer with unity gains (also known as a precision adder). The sum of the two input...

We acquired music from outer space in 2016 in order to carry on the great work of ray wilson-- and we are proud to announce another module in the series of new mfos eurorack modules, the multimode vcf We've taken ray's design and brought it up to date...

This module & SMT PCB was designed and manufactured with kind permission of “FONITRONIK” and Thomas Henry. It is the Supercontroller Circuit published in Polyphony Issue Sept./Oct. 1981 and his book “Build a better music...

Shades provides 3 channels of audio/CV processing which can be configured either as active attenuators or as attenuverters. A bicolor LED monitors the polarity and intensity of the audio or CV signal on each output. Unconnected inputs are normalized to...

This module requires the main PCB and the display sub-PCB. Streams provides two channels of extremely flexible signal dynamics manipulation. Each channel consists of an analog voltage-controlled filter and amplifier (VCFA). The response curve of the...

The AI Synthesis AI004 OTA VCF is a loving tribute to the MS-20 Filter. This OTA Voltage Controlled Filter uses the same filter structure as the venerable Korg MS 20 Filter. The filter is switchable between Lowpass and Hi Pass modes, and...

16hp Eurorack module Shelves brings to Eurorack modular systems something we are all very familiar with: the 4-band parametric EQ typically found in console channel strips. But this time, there’s CV control! The first band is a low-pass shelving...
